Hello guys,
I have a spectrum (FTIR) and I want to convert the spectrum to a barcode data and possibly plot it. This could be one spectrum or spectra.
Is there any matlab code that I can use to convert my data (Spectrum or spectra) to a barcode data?
see aatahced an example of the data I'm tryting to convert to a barcode. Column 1 is the wavenumber (x-axis) and column 2 is the intensities (y-axis).
Thank you.

Hi @Curious Mind,
While there is no direct MATLAB functionality which converts sample data into barcode, you can try out a combination ‘repmat()’ and ‘imshow()’ to generate barcodes of your desired lengths and complexities.
By changing the copy number in ‘repmat()’, you can determine the length of your barcode to be generated. Refer to the below example code for better understanding. The binary data is obtained by using a suitable threshold (here, applied on the intensities).
csv = readtable("Convert_To_Barcode.csv")
wavenumbers = csv{:, 1};
intensities = csv{:, 2};
% Normalize the intensities and store the results in normalized_intensities.
threshold = rand; % You can adjust this threshold as needed
binaryData = normalized_intensities > threshold
barcodeWidth = %set a specified value
barcodeImg = repmat(binaryData’,barcodeWidth,2)
figure;
imshow(barcodeImg,'InitialMagnification','fit')
The links to the respected documentations are given below:
Hope this helps.
